The rover is expected to touch down on Mars in February 2021. NASA says the rover will, “search for signs of past microbial life, characterize the planet's climate and geology, collect samples for future return to Earth, and pave the way for human exploration of the Red Planet.”

"As we get ready to launch this historic Mars mission, we want everyone to share in this journey of exploration," said Thomas Zurbuchen, associate administrator for NASA's Science Mission Directorate (SMD) in Washington. "It's an exciting time for NASA, as we embark on this voyage to answer profound questions about our neighboring planet, and even the origins of life itself."
